The results are pretty interesting. Over 800 people reported bugs between Fedora 18 Beta and Final, creating over 2300 new bugs in total. Those are stunning numbers for a 6-week period including Christmas holidays. A trimmed list of top contributors is below:

Test period: 2012-11-29 – 2013-01-15 (Fedora 18 Beta release – Fedora 18 Final release)
Total number of reporters: 814
Total number of new reports: 2311

…and also 710 other reporters who created less than 5 reports each, but 1164 reports combined!

1 The total number of new reports (including “excess reports”). Reopened reports or reports with a changed version are not included, because it was not technically easy to retrieve those. This is one of the reasons why you shouldn’t take the numbers too seriously, but just as interesting and fun data.2 Excess reports are those that were closed as NOTABUG, WONTFIX, WORKSFORME, CANTFIX or INSUFFICIENT_DATA. Excess reports are not necessarily a bad thing, but they make for interesting statistics. Close manual inspection is required to separate valuable excess reports from those which are less valuable.3 This only includes reports that were created by that particular user and accepted as blockers afterwards. The user might have proposed other people’s reports as blockers, but this is not reflected in this number.

I’m very glad to see that most of the top reporters are in fact not Red Hat employees. That suggests how strong Fedora community is. I’d like to specifically thank these top community contributors, namely Reartes Guillermo, Mikhail, Jan Teichmann, Steve Tyler, Chris Murphy, Gene Czarcinski, Dean Hunter, Heiko Adams, Max, Andre Robatino, Štefan Gurský, Niki Guldbrand and all the others that spent their personal time to help improve Fedora quality.

Of course, kudos also to anyone else who contributed, no matter whether they are mentioned in the matrix above or not. Without you, the bug reporters, we wouldn’t be able to keep Fedora 18 quality up, as it is (hopefully) now. So, thank you!

Recruitment pitch: If you haven’t participated in Fedora 18 release validation, we would love to see you in the Fedora 19 cycle (the test period will start in a month or so) or simply helping out to polish the currently stable Fedora 18 release. Please read QA/Join#Reporting_bugs_in_Fedora_releases, follow the announcements and talk to us in #fedora-qa on IRC and test list.

Thanks everyone!

When reading the statistics, please take it with a grain of salt. The numbers are not directly comparable. People might see some reports as more valuable than others. Some people tested a lot of components, but haven’t found many problems (but that also helps). Some people used their skills in other areas than Bugzilla or wiki matrices. This is not meant to be a comparison chart, but a well-meant “thank you” letter.
